Determine the distance to a galaxy (in Mpc) if it isfound to be moving away from us at a speed of 30,000km/s.
There are two optical telescopes operating at the exactsame frequency. The first telescope is a 16 m telescope that isplanned to be located at the L2 Lagrangian point 1.5 millionkilometers past the orbit of the Earth. The second telescope is a 2m telescope that is planned to be placed on the far side of themoon (average distance to the moon is 380,000 km from the Earth).The 16 m telescope has a greater light gathering power by a factorof _____ times? Enter your Numerical answer below. Round off youranswer to 2 decimal places.
HIPPARCOS was a scientific mission of the european spaceagency (ESA). It was the first space experiment devoted toastrometry, the accurate measurements of star positions, distance,parallaxes, and proper motions. If the measured parallax shift of astar is 0.120 arsecs, what is the distance to this star in lightyears? Repot your answer to 2 decimal places.
A comet is discovered that has an orbital period of 125years. Determine the average distance of this comet from the sun inAU. Report your answer to 2 decimal places.
